But I don’t know how to display the uploaded image. and also I want to know how to display all of the previous images. Please help me and show me some code! Many Thanks.

If you are storing the Image in SQL as an image data type I would use a custom http handler to display the images on the Page. I use something similar to

public class ImageHandler : IHttpHandler
{
    public bool IsReusable
    {
        get
        {
            return false;
        }
    }

    public void ProcessRequest(HttpContext context)
    {
        string imageid = context.Request.QueryString["ImID"];

        using (DataContext data = new DataContext())
        {
            var image = data.Products.Where(p => p.ID.ToString() == imageid).Select(p => p.Image).Single();
            context.Response.BinaryWrite((byte[])image.ToArray());
            context.Response.End();
        }
    }
}

To display the image just set the Image url to

ImageHandler.ashx?ImID={Id of the database entry}
